Application filed October 17, 1919. Serial 1T0. 331,315.

To all 10700770 it may concern 1 Bent known that L CLYDE Enter, a;

citizen of the United Fit-ates residing at Paul, in the county of liamseyi andtitate o1? liltinnesota, have invented a new and useful. ln'iprovement in .li-ini Tools, of which the following is a specification My invention relates to a rim tool which i is particularly adapted for use in connection with split steel. rims which are used for automobile pneuniatic tires and the device is ot a simple inexpensive design, the elements oi? which are particularly adapted to he held collectively together and unseparahle from each other so that they can be folded into a small, compact state. l

The invention is provided with means for locking; the elements in one position when the pivot points, which connect the same, are passed over their centers so asto firmly holdthe device locked in a set positionl The device is provided with recesses which open into a slot so as to connect the recesses with the slot to adjustahlyposition the ele ments of the device together, each recess being; so formed as to look a pin projecting from. the operating leverso that the lever can be operated-in either directionto move the elements of the device longitudinally to contractor expand a tire rim, as may be desired, when the pin notches.

Afurther important feature of the invention is in casting the notch engaging pin which projects tfrom the operating lever, in ten ral with the operating lever andwith a shoulder on its outer end which prevents the elements from being separated from the operating lever to hold the parts of the device collectively together. The slot torined in the element which carries the notches is formed the same. a

is engaged in one the In the drawings forming part of this specification: i

Figure 5 illustrates adetail oi? the device, showing the open formation of the slot before the elements are connected together.

Figure 6 is a crosssection on the line 66 of Figure 3.

Tn the drawing, the tire tool A is composed of rim engaging elements or arms 10 and 11 split rim B of a tireC when it is desired to contract the rim to remove the tire C from An. operating lever 13 is pivotally secured at 14 to the member 10 and is formed Wit-l1 a hook portion 15 on 1ts outer free end,

which is adapted to engage the arm 10 to limit the movement otthe level-1 3 in one direction. is i 1 i The member 11. is formed enlarged on its inner end with a longitudinally extendingslot or open portion 1.6, having a series of notches 1.7 which open into the slot 16; in the formation of the member 11., the slot 16 is formed with its sides 18 bowed outwardly, as illustrated in Figure 5.

An engaging .pm 19 is formed integral with the operating lever 13 and projects from one side of the same near the pivot point 14, the pin 19 being adapted to engage in the slot 16 and notches 17. The pin 19 is formed with a shoulder or head portion 20 on its outerend; which is insertedhin the opening or slot 16 when the sides 18 are bowed outwardly in connecting the member or element .11 with the operating arm 13 and the outwardly bowed sides 18 are then squeezed or forced inward :to cause them toextend approximately parallel with the longitudinally extending edges 21 between the notehes lf? so as to term a longitudinally equalwidth slot 16 on the inner end of the member ll, which is connected with the series of notches 17. Then the bowed sides 18 are squeezed inward. the sh oulder or'head 20 of the pin 19 is adapted to hold or lock'the member 11 connected with the operating arm 13 and member 10 against separation therefrom therebyholdingthe members ot the tool A collectively and unseparablv nrethcr, The members 10, 11 and 1 are or. a flat, thin nature and are )reterably formed of malleable cast iron. tne pin 19 with its head 20 being castintegrral with the member 1.3. a feature which is very important. The pin 19 is freely slidable in the slot- 16 so as to be adjusted into any of the notches 1?. In this manner the spread of the operating; arms 10 and ll otthe device A can be lengthened or shortened to adjust the same for different size rims, as the occasion ofi'ers.

Thenotches 17 are formed elongated so as to engage the pin 19 securely to allow the lever 13 to be noved in either direction to operate the arms or elements 10 and 1.1.

Thus byoperating the lever lJSthc arms can be drawn together or forced apart when the pin 19 is engaging in one ol the notches 17 without the pin19 becoming disengaged from the notch in which it is positioned.

Shoulders 22 are formed integral with the members 10 and 11 and project from the body portion of the members, being positioned near the engaging ends or hooks 12. and a strengthening rib 23 is to l-med projecting from. the body portion of the members 10 and 11 to brace and support the shoulders 22. The shoulders 22 are adapted to engage the inner portion of the split rim B to expand or close the rim by OPQIelilllI the lever 13 in the proper direction to move the members 10 and 11 longitudinally when the engaging pin '19 is set in the desired notch. The tire rim is freely and easily contracted by use oi. the tool A when the books 12 are brought into engagen'lent with the rim B. and the lever 13 is moved into closed position, illustrated in Figures 3 and WVhen the lever 13 is moved into this position the center of the pin. 19 extends over the center of the: pivoting point 14, thus looking the device A in contracted, closed position, while the hool: 15, "formed on the free end of the lever 13, is adapted to engage the member 10 and form a stop for the operating lever 13. In a device of this kind it is very desirable that the members be connected together in a simple manner so as not to be separated :from each other and still to be freely adjustable to various lengths for different" size rimsa My device is so constructed that it very simple and inerzpensive to manufac- ,mmand While it is desirable to make it of .rnallea'ble iron, it can be obviously constructed in any other suitable manner. It is an important l'eature that the member ll be formed with bowed sides and an enlarged recess 16. which is later 'i crced together so as to form a longitudinal equal slot H3 in hold the pin 19, the shoulder 20 ol' which prevents disengagement o l the operating! arm tromthe member 11 and hv torming the pin 19. and shoulder Ql) into .l with the operating lever 13-, a eonsidez c expense in the manut'acture ot my device is eliminated. making a practical operative device. Further. the peculiar shape of the notches lT. which open into the slot H3 is ir-iportald rm as to hold or engage the pin If) in e llur direction of the operation or movcnumt ol' the operating lever 13. By parsing the centers of the pivot points of the members over each other in contracting arim, the members loci-1 t .mselves together and this i:-= a Featur which is most desirable in a device ad this nature.
